Research On Cruise Missile's Precise Air-to-Terra Attacking

Our country's cruise missile enterprise had a big disparity with the international advanced level, especially the missile's firing accuracy, although had having the big development. If purely begins from the hardware, the fund is big, and it is impossible to obtain the great enhancement in the short time. It is a more feasible method to realize the missile's firing accuracy, by studying scene matching, track following, the middle guidance law and the terminal guidance law.This thesis uses fuzzy changing the gain proportion guidance to control the yaw angleψv and the pitching angleθ, and to realize following track, with the predetermined track, which had been designed by hierarchical track planning with Voronoi diagram.A good many missiles not only hope to obtain slightly miss distance, but also hope the best posture when attacking goal. In this way, the warhead will display biggest efficiency, and obtain best execution. Like the antitank missile can vertically attack front armor, or attack the weak part of armor with the big arrival angle to obtain the greatest depth of drill and approach angle about 90o. This thesis proposes one kind of variable universe fuzzily variable the structure terminal guidance Law to realize vertical precise attack.This thesis also proposes the circle projection matching algorithm, which solves matching problem of the pictures with the free angle revolved. At the same time, the thesis has analyzed the influence to the circle projection matching algorithm of the noise, the illumination and the change of gradation. Then the thesis constructed the algorithm. This method is good compatibility to the noise, the illumination and the change of gradation.Finally the thesis realizes cartoon of cruise missile's cruise and attacking target with VC++ and the OpenGL.
